Looking in the archives of Haifa's municipal government, I have found much material relating to the 1976 chess Olympiad. Here is one example: the top photo a certificate for participation in the 'Haifa Chess Olympiad Display Window Contest.' This context was a contest among local businesses to decorate their display windows in a chess-related and, especially, Olympiad-related way, by using the Olympiad's symbol, etc.
The bottom photo is an advertisement from the August 1976 Haifa's Merchants' General Union publication, asking 'Haifa Merchants' to 'properly decorate their businesses', and that the union can give them appropriate decorating material. They also suggest giving a discount to 'all comers who wear the Olympiad's symbol.'
